I lecture you.
Here my imgur, thanks for the suggestion.
Further tip: I assigned ENTER also to my Razer DeathAdder side button, back button, so I am always in a thumb click distance for editing any midi item from arrange, same thumb click to return back to arrange. It works as you can see in this image. Now you can keep your workflow and complain here. For me these are improvement areas:
-vertical zooming so a few notes are free on top, e.g. 5 notes empty lines at top, similar as emacs can do when using Control-l
-single item selections do not behave optimally
